Abstract: The present disclosure provides a downlink control signaling sending method and device. The method includes: determining, by a base station, a first transmission type of a first terminal device and a second transmission type of a second terminal device; and sending demodulation information to the first terminal device according to the first transmission type and the second transmission type by using downlink control signaling, where the demodulation information is used to instruct the first terminal device to demodulate a transmission signal of the first terminal device that is received by the first terminal device. In this way, content of the demodulation information to be sent is specifically determined, so as to effectively resolve a problem that, during pairing at a plurality of layers, when different power ratios are configured on different subbands, a large amount of signaling needs to be consumed for notification to the first terminal device.
